It's not the GeForce BGA. I reworked it last night. No change in behaviour.
that is the one thing that really gets me with apple stuff… the MBP/iMac g5 and intel/Powermac G5, etc They let this stuff get way too hot!all because they don't want to hear a little fan noise!
All of those machines you listed are certainly capable of moving some serious air, I wouldn't really be prepared to say cooling fans are the problem. Perhaps the layout of the heatpipe or the fact that these integrated circuits get extremely hot by nature is a possibility, but i'd be more inclined to say it's a combination of the heat output and the results of the Restriction of Hazardous Substances directive that's screwing these machines over.
